The previous analysis incorrectly identified gaps on the send side. With crank buffering, output validity and deferred transmission are achieved: messages only reach RemoteHandle via the run queue, which means the originating crank has already committed. The remaining gaps are on the receive side: - Done table for exactly-once delivery (deduplication) - FIFO enforcement for ordering Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Note
Low Risk
Documentation-only change that reclassifies protocol property coverage; no code paths or runtime behavior are modified, but it may influence engineering priorities if misinterpreted.
Overview
Updates
docs/ken-protocol-assessment.mdto state that crank buffering fully achieves send-side output validity and deferred transmission, since messages reachRemoteHandleonly after the originating crank commits via the run queue.Reframes the remaining work as receive-side gaps only, adding concrete failure scenarios and outlining needed mechanisms for exactly-once deduplication (a
Donetable / processed-seq tracking) and FIFO ordering (buffer/reorder out-of-order messages), and refreshes the summary/progress tables accordingly.Written by Cursor Bugbot for commit a7446e5. This will update automatically on new commits. Configure here.
